Electronic Raman transitions (3A→3E(C3)) have been observed between the trigonally split components of the 3T1g(Oh) ground term of the vanadium(III) hexa-aqua cation in guanidinium vanadium sulphate hexa-hydrate. The magnitude of the trigonal field splitting is considerable, ~2720 cm-1, which is consistent with expectations based on the stereochemistry of the [V(OH2)6]3+ complex. It is shown that a satisfactory reproduction of the electronic Raman band profile can be obtained only by assuming a (3A⊕3E)⊗e vibronic coupling model.
